Specification of Letters Patent.

Patented March 19, 1907.

Application filed March 14:. 1904- Serial No. 198,136-

To all w/tmn it may concern:

Be it known that we, WALTER A. STEB- mm, a citizen of the United States of America, and HILMER BERGSTROM, a subject of the King of Sweden, both residing at the city and county of Denver and State of Colorado, have invented certain new and useful .lmproveinents in Turn-D own-Collar Folders and Shapers; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Our invention relates to improvements in turn-down-collar folders and shapers, our object being to provide a machine adapted to automatically and quickly fold a turn-down collar and afterward impart to it the proper sha e.

O in further object is to rovide an apparatus of this class which sha 1 be comparatively simple in construction, economical in cost, reliable, durable, and eliicient in use; and to these ends the invention consists of the features, arrangements, and combinations hereinafter described and claimed, all of which will be fully understood by reference to the accompanying drawing, in which is illustrated an embodiment thereof.

In this drawing, Figure 1 is a vertical longitudinal section of the machine, taken on the line 1 1, Fig. 2. Fig. 2 is a top or plan view of the machine, parts being shown in section and the upper dampening-wheel and one of the gears removed. Figs. 3, 4, 5, 6, 7, and 8 are sections taken on the lines 3 3, 4 4, 5 5, 6 6, 7 7, and 8 8, respectively, of Fig. 2. Fig. 9 is a transverse section taken through the shaping-rollers. In this view the'position of the gears of the shaping-rollers is indicated by dotted lines. Fig. 10 is a longitudinal section taken through one of the said rollers. Fig. 11 is a plan view of a collar of the description which our improved machine is adapted to fold and sha e. Fig. 12 is a transverse section of the co lar.

. The same reference characters indicate the same parts in all the views.

Let A designate a suitable table provided with supporting-legs A and A which, as

shown in the drawing, are made fast to a suitable stationary support by means of fastening devices. The top of the table, as shown in plan view in Fig. 2 of the drawing, is preferably curved horizontally to conform to the general curvature of the collar to be folded. Mounted on the forward or left-hand extremity of the table, referring to Figs. 1 and 2 of the drawing, is a frame B, composed of upright parts B and a transverse part B Slidably mounted in the transverse part B is a part C, consisting of a handhold upper part C and two vertical legs C and The lower extremity of the le C is connected with aholder C for a small wheel C whose periphery is preferably beveled on both sides or V-shaped in cross-section. The lower extremity of the arm C of the part C is connected with a holder C for a roller 0, cooperating with a roller C the latter being journaled in the top A of the table Between the wheelholder C and the under surface of the transverse part B is located a coil-spring C, which normally has a tendency to hold the wheel C at its lowest limit of movement. Also between the roller-holder C and the under surface of the part B is located a coil-spring C which surrounds the arm C Attention is called to ihe fact that a slot is cut in the top of the table where the roller C is located to permit the latter to protrude slightly above the top of the table in order that it may cooperate with the roller C The wheel (J is a guide-wheel,- and the rollers C and C have their axes extending at an angle to the axis of the wheel C whereby as a collar is passing over the table when the machine is performing its function the tendency of the rollers is to feed the collar in a direction extending at an angle to the horizontal curvature of the tables top. When the device is acting on a collar, the guide-roller C engages the collar at the seam or folding-line on the inside.

Slightly in the rear of the guide-roller C are located the two dampening-rollers D and D. The roller D is mounted on a shaft D journaled in suitable upright parts D connected with the opposite sides of the table. The periphery of this wheel is preferably faced with rubber or other suitable soft material. Mounted above the wheel D is a receptacle D, containing water and having a wick or fibrous piece of material D one eX- tremity of which is in communication with the water of the receptacle, while the other extremity engages the periphery of the wheel as the latter rotates, whereby the face of the wheel is kept damp or moist sufficiently for the purpose hereinafter explained. The wheel D is so arranged that the lowest part of its periphery is very close to the plane of the upper surface of the table, whereby it cooperates with the uppermost part of the periphery of the wheel D, which projects upwardly through an opening formed in the table, the highest part of the periphery of the wheel D projecting slightly above or occupying a position on a level with the upper surface of the table. The wheel D is made fast to a transverse shaft D extending underneath the table. This wheel D rotates in a quantity of water D placed in a tank or receptacle D, suitably supported under neath the table. The shaft D which extends underneath the table as aforesaid, is provided at one extremity with fast and loose pulleys D whereby the shaft may be operated from any suitable motor or source of power. Also mounted on the shaft D on the side of the table adjacent the pulleys D is a gear D, which meshes with a gear D fast on the shaft D whereby the last-named shaft is operated. On the extremity of the shaft D remote from the pulleys D is located another gear D, which meshes with a gear D, the latter meshing with a gear D. The gear D is mounted on a shaft 1), journaled in the table, while the gear D is fast on a shaft D journaled in the leg A of the table. To this shaft D is made fast a gear D which meshes with two gears D and D made fast to shafts D and D respectively. The shafts D D and D are provided with shaping-rollers D D and D respectively, located at the rear extremity of the table.

Between the shaping-rollers and the dampening or moistening rollers a plate E is secured to the upper surface of the table by suitable fastening devices E. Beyond the fastening edge of this plate the latter is cut away underneath, leaving a space E between the lower surface of the plate and the top of the table. The forward extremity of this plate is bent upwardly slightly, as shown at E, forming a sort of mouth to receive the collar as it leaves the dampening rolls or wheels. The forward extremity of this plate occupies a position parallel with the top of the table; but immediately in the rear of the forward extremity of the plate the latter is bent upwardly from the table, as shown at E in Fig. 4, the edge E of the bend being in line with the seam or folding-line G of the collar G. This part E is gradually bent upwardly, diminishing its interior angle as the rear extremity of the folding-plate is approached until finally the part E is doubled over upon the upper surface of the body of the plate and merges thereinto, as shown at t in Fig. 1. For instance, where the section indicated by the line 5 5 is taken the part E is at right angles to the body E of the )late. (See Fig. 5.) \Vhere the section indicated by the line 6 6 is taken, the part E of the plate forms the oblique angle indicated in Fig. 6, while where the section indicated by the line 7 7 is taken the plate E is merged into the body E of the plate or removed entirely since the flat or horizontal part of the plate takes its place and the angular part E is no longer needed.

At the point where the part E of the plate E begins to bend upwardly a cooperating correspondingly bent or inclined plate F is secured to the table just outside or to the left of the part E (see Fig. 4,) a sullicient space being left between the parts E and F to allow the part G" of the collar to pass between them. As the rear extremity of the table is approached the plate F is bent to keep pace or correspond with the bend of the plate E", whereby as the collar is fed along the top of the table the part l" passes between the body of the plate E and the top of the table, and the part G is gradually bent over upon the part G through the instrumentality of the parts F and E, as indicated in Figs. 3 to 7, inclusive, of the drawing. It will be seen that where the section indicated by the line 7 7 is taken, while the plate part E is done away with, the partl occupies a horizontal position parallel to the body of the plate E and slightly raised above the same, le ving a spacefor the part it" of the collar to pass between the plate E and the part F. Hence it will be seen that after the collar is fed over the top of the table and acted on by the plate parts E, E, and F, shaped as described and illustrated, the part G which when the operation commenced lay in the same plane with the part G, will be folded down upon the part G, as is re quired. After leaving the folding-plates or cooperating folding-plate parts the collar passes first between. the rollers D and D and afterward between the rollers D and D whereby the collar is shaped or caused to curl or bend as is required for use.-

In rear of the moistening wheels or rollers D and D and. located above the plate E is a roller H, whose lowest portion passes through a slot formed in the body of the plate E, whereby the lowest part of the roller cooperates with the uppermost part of a cooperating roller H, journaled. .in an opening formed in the top of the table, and whose uppermost portion lies in the same plane or projects slightly above the plane of the upper surface of the table, whereby the two rollers H and H cooperate to act upon the part G of the collar during the travel of the latter through the folding-plates heretofmte described. The axis of these rollers H and H extend slightly at an angle to the horizontallycurved path of the collar, this path being indicated by the broken line I on F ig. 2 of the drawing, whereby there is a tendency on the part of the rollers H and H to cause the collarto travel at an angle to its real path, whereby the seam G of the collar is made to follow the line of the angle E or the line of the bend between the horizontal part and the part E of the foldingplate E as the collar travels along over the table. The dampening-wheels are so arranged that a narrow space G on the part G of the collar adjacent the seam or folding-line G is moistened in order to facilitate the folding operation after the collar leaves the moistening wheels or rollers. Between the rollers H and H and the mo1steningwheels is a small wheel J, mounted in a depending part J of an arm J hinged at J to a stationary part J made fast to one edge of the table, being operation the edge remote from the fastening devices E of the folding-plate E. The periphery of this wheel J is beveled on both sides, forming a V-shaped edge adapted to engage the collar on the folding-line G as the latter is acted on by the folding devices. The lowest part of the periphery of this wheel J passes through a narrow slot formed inthe body of the plate E on the line of the angle E and consequently on the folding-line G of the collar. This wheel forms a guide to cause the collar to travel in the circular path over the top of the table, as heretofore explained, and its axis lies at an angle to the axis of the feedrollers H and H. The arm J 2 is acted on by a leaf-spring J whereby the wheel is held under suitable tension to properly perform its function.

The lower roller H is connected with a shaft H provided at one extremity with a pulley H connected with a belt H which engages a larger pulley H fast on the operating-shaft D whereby the necessary rotary movement is imparted to the roller H. Attention is called to the fact that a belt H connects a pulley H fast on the shaft D, with a small pulley H fast on the spindle H of the roller C whereby the necessary rotary movement is transmitted to the latter.

From the foregoing description the use and of our improved machine will be readily understood. At the beginning of the folding operation a collar of the construction shown in Big. 11 is first passed between the rollers O and C the roller C together with the guide-wheel 0*", being first lifted slightly upwardly in order to place one extremity of the collar in position. Then, assuming that the machine is in operation, by virtue of the construction and connections heretofore ex plained the collar is fed rearwardly on the table, the guide-wheel C engaging the seam or folding-line G of the collar and being so located as to cause the latter to travel in an arc of large radius, as indicated by the broken line I on fig. 2 of the drawing. As any portionof and C and the guide-wheel C it passes between the dampening-wheels D and D, whereby a narrow space G adjacent the foldingline G is dampened. The collar then passes, by virtue of the feeding movement imparted by the rollers O and C and whereby through the instrumentality of the guide-wheel J and the feed-rollers H and H, together with the peculiar shape of the plates E and F and the plate part E the part G of the collar is folded over and pressed downwardly upon the part G as heretofore explained, after which the collar is passed between the shaping-rollers D D and D, as already explained.
